Based on the construction of this object—digitalization—the aim of this article is to
outline a sociological investigation, situated within sociological theory, that offers a critique of
digital modernity through interdisciplinarity among Hartmut Rosa’s sociology (which
addresses the phenomenon of digital alienation), Jean M. Twenge’s social psychology (which
deals with the emergence of digital depression), and Manfred Spitzer’s neuroscience (which
points to the rise of digital dementia).
Digitalization of the World: Technological Ultra-Acceleration in Contemporary
Modernity
Contemporary, or late, modernity is the expression of an acceleratory surge that has
been propelled since the final decades of the twentieth century (Rosa, 2019a, p. 428). With
regard to advances in digital technology, this is the historical period in which the global
consolidation of the internet, the construction of the web, and the widespread presence of
electronic computers, smartphones, portable devices, and gadgets in everyday life become
entrenched, alongside the massive use of social networks (especially Facebook, WhatsApp, X,
Instagram, and TikTok). The digital revolution of our time, combined with the technical
acceleration of communication media, instant transmission, and information systems (big data,
algorithms, databases), represents an unprecedented stage of technological ultra-acceleration

Indeed, the digitalization of the world emerges as a process resulting from technological
ultra-acceleration that drives contemporary digital revolutions. As Evgeny Morozov (2018, p.
7), author of Big Tech: The Rise of Data and the Death of Politics, argues, digital technology
is not merely applied science—as suggested by more simplistic philosophies of technology—
but rather a tangled web of geopolitics, global finance, unrestrained consumerism, and the
accelerated corporate appropriation of our most intimate relationships.
In this sense, the concept of digitalization of the world refers to a new social system
that, from the perspective of its technological infrastructure, is based on the formation of a
network society (Castells, 2005)—digital networks of devices that generate, process, and

Technical and technological acceleration, developed in modernity through processes of rationalization and
modernization, constitutes a central category in Rosa’s sociological thought. It is conceived as an essential driving
force of the capitalist mode of production, transforming values, social change, social action, and human
subjectivity. Among the most evident manifestations of this phenomenon are the acceleration of transportation,
communication media, the production of goods and services, data flows, and information technology. From this
perspective, the acceleratory intensification observed in the transition from the twentieth to the twenty-first
century—which propelled the digital revolutions—represents a qualitative leap in processes of modernization and
rationalization. It can be classified as a form of technological ultra-acceleration that intensifies and deepens
preexisting patterns of acceleration, particularly in the sphere of data and information technology (Rosa, 2019a).
